A complete set of numerical invariants for a subfactor

摘要

We show that certain numerical invariants associated naturally to a subfactor planar algebra constitute a complete family in the sense of determining the isomorphism class of the subfactor planar algebra.In the course of the proof, we show also that planar algebra isomorphisms of subfactor planar algebras can always be chosen to be *-preserving. This latter statement generalises the fact that 'Hopf algebra isomorphisms of finite-dimensional Kac algebras can be chosen to be *-preserving'. (C) 2004 Elsevier Inc. All rights reserved.
